Abstract
In order to review the seriously damaged railway embankment due to the 2004 Niigata-ken Chuetsu Earthquake and evaluate the seismic performance of reconstructed embankment which is geosynthetic-reinforced soil wall with rigid facing, the seismic stability and residual deformation analyses were conducted. The method of seismic stability analysis was executed by the limit equilibrium method and the seismic residual deformation analysis was applied Newmark's sliding model to the slip circle. As a result, it is shown that the simulated residual deformation due to earthquake is corresponding to the actual magnitude of failure and predicted one become to the effective and practical index of the seismic performance of reconstructed embankment.
